WINSTON-SALEM, N.C., May 30, 2012 /PRNewswire/ -- Tengion, Inc. (NASDAQ: TNGN), a leader in regenerative medicine, today announced that its Board of Directors has approved a reverse split of its common stock at a ratio of 1-for-10. The Company's common stock will begin trading on a split-adjusted basis when the NASDAQ Capital Market opens on June 14, 2012.

The reverse stock split, which was approved by Tengion stockholders, is intended to enable Tengion to regain compliance with the NASDAQ minimum bid requirement to maintain the Company's common stock listing on the NASDAQ Capital Market. There can be no assurance that the reverse stock split will have the desired effect of raising or maintaining the closing bid price of the Company's common stock.

The reverse split will reduce the number of outstanding shares of the Company's common stock to approximately 2.5 million shares. Fractional shares as a result of the reverse stock split will be rounded up to the next whole number. Proportional adjustments will be made to Tengion's outstanding warrants and stock options. The Company's authorized shares will remain unchanged.
